LIQUID-SPRAYER.

Specification of Letters Patent.

Patented Aug. 27, 1907.

Application filed June 13,1906. Serial No. 321,439.

To all whom it may concern:

Be it known that I, LEWIS AUGUSTUS AsrrNwALL, a citizen of theUnitedStates, residing at Jackson, in the county of Jackson and State ofMichigan, have invented a new and useful Improvement in Liquid-Sprayers,of which the following is a specification.

My present invention relates to improvements on the liquid sprayingdevices described and shown in LettersV Patent heretofore granted to me,and the main objects of my invention are to place the shafts on a higherlevel so as to be more nearly horizontal and to obtain a more perfectadjustment for changing the height of the spraying nozzles; theseobjects being more or less complementary to one another because wherethe shafts are lower down it is not possible to obtain the desiredadjustment of the spraying nozzles.

In the device of my present invention I employ angular corner postsmounted upon and secured to the main frame and inclined brackets restingat their lower ends upon the main frame and connected to the adjacentends of auxiliary frame members. The upper ends of the brackets carry across member and the shafts are connected to and supported by saidcorner posts and cross member.

A second cross member is connected to the shafts forward of theaforesaid cross member and said cross members serve to make the shaftsmore rigid and they srrve as a support for the draft bar to which ahorse or other animal drawing the machine is secured.

I employ substantially horizontal bars placed longitudinally of theliquid spraying machine for carrying the spraying devices, and whichbars are pivotally connected at one end to the corner posts and aresuspended by vertical adjustable bars connected to the shafts so thatthe desired height may be obtained for the spray; ing devices; and theextent of this adjustment is greater than that which I have heretoforebeen able to employ.

The forward ends of the bars carrying the spraying devices are bent atright angles and preferably made round and they support swivel barscarrying the spraying nozzles, and these swivel bars are adjustable onthe central pivot and the nozzle connections secured at the ends of theswivel bars are adjustable from a vertical to any desired inclinedposition.

In the drawing, Figure l is a side elevation and Fig. 2 a plan showingthe devices of my improvement.

The parts shown in the drawing, and which are common in liquid sprayingdevices heretofore employed by me and shown and described in LettersPatent granted to me, comprise the liquid holding barrel 2, the agitatordevice 3 pivotally mounted upon the liquid holding barrel having apaddle part going down into the barreland an operating arm extendingdownward to other parts of the mechanism, a pump 4, a pump beam 5 foractuating the piston of the pump, an air chamber 6, asprocket 7 on themain axle 13, a pinion 8 on an auxiliary axle and a chain or band 9passing around the same so that the rotation and the power of the mainaxle are communicated through the chain or band from the sprocket to thepinion, a throw-out lever l0, a yielding frame ll and spring l2connecting the pump beam to devices mounted on the auxiliary axle. Theseparts are supported upon a main frame a and I4 represents a main wheelin dotted outline and l5 a pipe for the liquid extending from the liquidholding barrel to the pump.

The special features of my present invention comprise the auxiliaryframe members b b1 which are parallel with one another, extendlengthwise of the machine and are supported upon and secured to the mainframe. Upon the opposite forward corners of the main frame are angularcorner posts c, d secured to the main frame, and `c f representforwardly inclined brackets. These brackets rest upon the main frame; infact they are shown as having a notched portion at the back to rest uponthe cross bar of the main frame and they extend alongside'of andparallel with the projecting ends of the auxiliary frame members b b1and they are securely bolted to these frame members so that theirposition for support and strength is secured.

A cross member g is securely fastened to the forward higher ends of thebrackets c f and the ends of this member project beyond the brackets.VThe shafts are represented at L i, their rear ends resting upon,supported by and secured to the said corner posts c d. These shaftsextend under the projecting ends of the cross member g and they aresecured thereto by bolts;

therefore the shafts have a firm support, between whicl1- and theirconnection to the rigidly secured brackets cf there is no chance forsaid shafts to become loosened or misplaced and when so connected withthe machine in operative position these shafts are substantiallyhorizontal.

I employ a second cross member lc forward of the cross member y, theends of which rest upon and are Ibolted to the shafts h fr', said crossmember serving to make the shafts even more rigidly built. At the centerof these cross members g 7c I place a draft bar l, which draft-bar maybe of any desired character. to which the horse or other animal drawingthe machine is to be secured by suitable harness.

The main frame, the auxiliary frame members, the shafts and the crossmembers are preferably made ot' wood, while the angular corner posts andforwardly inclined brackets are preferably made of metal not only forstrength but to form a rigid connection between the parts.

I employ bars of metal m n which occupy substantially a horizontalposition. These bars are pivotally connected at their rear ends to thesides of the corner posts c d and their forward ends are bent outwardlyat substantially right angles to the main portions of the bar and arepreferably rounded; these latter parts being indicated at lm1 n1. Tosupport the said bars m '1t and their bent ends and to regulate theadjustable height thereof I employ vertical bars o o1 provided with aseries of holes spaced apart and on the shafts there are support pins rr which are adapted to pass through any one ol the holes of the saidvertical bars o o1; the ends ol said support pins being preferablythreaded to receive a nut and washer which serve to securely clamp thesaid vertical bars to said support pins, it being understood of coursethat said vertical bars at their lower ends are pivotally connected tothe bars m n.

I provide transversely placed bars s t secured by swivel connections st1 to the bent ends m nl of the bars m n; said bars s t being adapted toswing on the pivots 16 16 of said swivel connections from a transverseposition io an inclined position in either direction. To the respectivebars t are secured the sprayingl nozzle devices.

I prefer to make the swivel connections sl t1 in part tubular so thatthe pipes 1811er the spraying liquid may be connected thereto and thebranching pipes 19 for the spraying liquid may extend out therefrom tothe spraying nozzles u tf, and 17 represents a pipe and its couplerwhich extends from the air chamber 6 conveying,I the liquid for sprayingto the pipes 18.

The pipes 18 and 19 may be metal pipes or rubber pipes or hose which itis preferable to employ because the rubber hose is free from anytcndsncy to corrode and clog the nozzles with sediment produced by thevcorrosion as is the case with metal pipes.

The swivel connections's/ t form a protection to the rubber hose.

I claim as my invention:
